I am putting together an upper for my match long-range AR in 224 Valkyrie so I can shoot thousand yard prone matches. Going through my goodies, I found that I have an unopened box of Berger 90gr bullets ideal for the Valkyrie.

My question, it anyone here has the Berger reloading manual, could you please check to see it it has any load recommendations for the 224 Valkyrie round?

Gentlemen, I realize that I can Google some loading data, but I would like to see what the bullet manufacturer recommends.

Burger's Loading data isn't from cartridges fired in a test barrel or even a test rifle! it is from a computer program similar to Quick Load.

Hodgdon's loading publication for 2019 (newest I have) has a 90 grain Federal bullet and about 8 powders fired from a 24" pressure barrel. That is the wrong barrel length, the wrong gun & the wrong bullet. I think you will find that this and the internet info are going to be your best source.

BUT:

Have you tried calling Berger?

I don't load this round, but have a friend that does. In my quick research I saw that 224V Max Load runs about 2 grains over 223 R Max Load for the same powder. That is pretty sketchy to go by but take a 223 Rem max load you like for that bullet and work up from there in 2 or 3 tenth grain increments. You don't get to milk the forum for this one, you have to do the testing yourself.

My 223 R long range bullet is either a 77 gr. Berger VLD or a 75 gr. Hornady A-Max over 26.7 gr of Varget using a 12" drop tube. The OAL is way long! it is "Bumping" the lands in my target Savage. The Savage rubber over molded factory stock, it will produce 5" groups at 1000 yards, with a BR stock that is pillar bedded and torqued to 65 inch pounds, the groups are 3"! I have a choice of several brands of brass, but surprisingly Lake City gets the best performance. I use Remington 7 1/2 primer, There are no pressure signs but I'm sure it is over SAMMI limits. If my Memory is correct I'm at just under 3100 fps. I don't see any way for an AR to safely us ammo like this, You can still hit target with AR's at 1000, but you time in flight, and Mid Range Trajectory expose your bullet to more extreme environmental influences.

My friends loading of this round in several bullet weights brought him back to 77-80 grain bullets (he only uses Sierra Match Kings and Hornady A-Max). I argue that you loose too much powder capacity with anything over 69! But he wants to run with the big dogs at 1000.

In the days of 308 Service Rifle, many shooters used a much lighter bullet and powder charge at 200 & 300 yards and the full power 168's or 175's at 600, to save on cost and recoil on them. I would think a under 500 yard load and an over 500 yard load (either 2 different scopes, or good records on the ammo boxes) would be very doable for the 224V.
